1) Package mounted on PCB 80 × 80 × 1.5 mm³; 35µ Cu; 5µ Sn; Footprint only; zero airflow.
2) Measured to pin 2.
3) Measured to pin 5.
Optimum reliability and life time are guaranteed if the junction temperature does not
exceed 125 °C in operating mode. Operation at up to the maximum junction temperature
of 150 °C is possible in principle. Note, however, operation at the maximum permitted
ratings could affect the reliability of the device.
